How does underscore.isEqual work?

_.isEqual() is a method from the Underscore.js library that recursively compares two values and determines if they are equivalent, returning a boolean value. The comparison is based on the value's types and properties, and the method can be customized by passing in a callback function to handle specific cases. For example, the method can handle comparisons of arrays and objects with varying property orders or extra properties, as long as the key-value pairs match in content and order.

* @example
*
* var object = { 'a': 1 };
* var other = { 'a': 1 };
*
* _.isEqual(object, other);
* // => true
*
* object === other;
* // => false

const object1 = { a: 1, b: 2 };
const object2 = { a: 1, b: 2 };
const object3 = { a: 1, b: 3 };

_.isEqual(object1, object2); // true
_.isEqual(object1, object3); // false

In this example, _.isEqual is used to compare two objects object1 and object2, which have the same properties and values, so the function returns true. The function is also used to compare object1 and object3, which have different values for the b property, so the function returns false.
